Dataset Derived CMS 7TeV pp CERN-LHC Parent Dataset:
Run2011B_DoubleElectron dataset in a NanoAOD-like research-level Ntuple format for CMS Run1 data, readable with bare ROOT or other ROOT-compatible software, and containing the per-event information that is needed in most generic analyses. In contrast to the CMS NanoAOD which is derived from MiniAOD, this dataset is processed directly from the AOD format with code provided by the CMS open data group. Not all variables are available. Nevertheless, there is a large overlap in functionality and content between this format and the standard NanoAOD such that common analyses are possible.
The dataset is provided as a collection of root files. Run2011B_DoubleElectron_merged.root contains the separate files merged into one file. This dataset was processsed from the primary dataset in AOD format linked below.
The dataset was produced with the software available in the record linked below.
These data were processed from the primary dataset using only the validated runs.
You can access these data through XRootD protocol or direct download, and they can be analysed with common ROOT and Python tools. See the instructions for getting started in
